Cycolor
Cycolor is a tradename for a color printing process that uses a special film coated with millions of capsules filled with cyan, magenta, or yellow dyeprecursors, acrylic monomer, and photo-initiators. When exposed to red, green, and/or blue light, the contents of the respective capsules polymerize imagewise, and therefore become hard and unbreakable. The film is then pressed against specially treated paper that will complete the dye molecule, and the capsules that have not hardened in the previous process break, releasing their contents onto the paper. Cycolor was developed by Mead Imaging, a start-up created and funded by Mead Corporation, in the 1980s in Miamisburg, Ohio. It was based partially upon the same technology as carbonless paper, which has largely been rendered obsolete. Although the technology was very successful, the cost was significantly higher than the then emerging toner-based or ink-based systems seen today for color printing.

CMYK Color Model
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation ''CMYK'' refers to the four ink plates used: cyan, magenta, yellow, and key (most often black). The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called ''subtractive'', as inks ''subtract'' some colors from white light; in the CMY model, white light minus red leaves cyan, white light minus green leaves magenta, and white light minus blue leaves yellow. In additive color models, such as RGB, white is the ''additive'' combination of all primary colored lights, and black is the absence of light. In the CMYK model, it is the opposite: white is the natural color of the paper or other background, and black results from a full ...

Color Printing
Color printing or colour printing is the reproduction of an image or text in color (as opposed to simpler black and white or monochrome printing). History of color printing Woodblock printing on textiles preceded printing on paper in both East Asia and Europe, and the use of different blocks to produce patterns in color was common. The earliest way of adding color to items printed on paper was by hand-coloring, and this was widely used for printed images in both Europe and East Asia. Chinese woodcuts have this from at least the 13th century, and European ones from very shortly after their introduction in the 15th century, where it continued to be practiced, sometimes at a very skilled level, until the 19th century—elements of the official British Ordnance Survey maps were hand-colored by boys until 1875. Early European printed books often left spaces for initials, rubrics and other elements to be added by hand, just as they had been in manuscripts, and a few early printe ...

Cyan
Cyan () is the color between blue and green on the visible spectrum of light. It is evoked by light with a predominant wavelength between 500 and 520 nm, between the wavelengths of green and blue. In the subtractive color system, or CMYK color model, which can be overlaid to produce all colors in paint and color printing, cyan is one of the primary colors, along with magenta and yellow. In the additive color system, or RGB color model, used to create all the colors on a computer or television display, cyan is made by mixing equal amounts of green and blue light. Cyan is the complement of red; it can be made by the removal of red from white. Mixing red light and cyan light at the right intensity will make white light. It is commonly seen on a bright, sunny day in the sky. Shades and variations Different shades of cyan can vary in terms of hue, chroma (also known as saturation, intensity, or colorfulness), or lightness (or value, tone, or brightness), or any combinat ...

Magenta
Magenta () is a purple-red color. On color wheels of the RGB color model, RGB (additive) and subtractive color, CMY (subtractive) color models, it is located precisely midway between blue and red. It is one of the four colors of ink used in color printing by most Color printing, color printers, along with yellow, cyan, and black to make all the other colors. Magenta is a color made by mixing red and blue. The tone of magenta used in printing, Shades of magenta, printer's magenta, is redder than the magenta of the RGB (additive) model, the former being closer to Rose (color), rose. Magenta took its name from an aniline dye made and patented in 1859 by the French chemist François-Emmanuel Verguin, who originally called it ''fuchsine''. It was renamed to celebrate the French-Sardinian victory under French Emperor Napoleon III at the Battle of Magenta against the larger army of the Austrian Empire on 4 June 1859 near the Italian town of Magenta, Lombardy, Magenta, at the time in Au ...

Yellow
Yellow is the color between green and orange on the spectrum of light. It is evoked by light with a dominant wavelength of roughly 575585 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity. Carotenoids give the characteristic yellow color to autumn leaves, corn, canaries, daffodils, and lemons, as well as egg yolks, buttercups, and bananas. They absorb light energy and protect plants from photo damage in some cases. Sunlight has a slight yellowish hue when the Sun is near the horizon, due to atmospheric scattering of shorter wavelengths (green, blue, and violet). Because it was widely available, yellow ochre pigment was one of the first colors used in art; the Lascaux cave in France has a painting of a yellow horse 17,000 years old.

Miamisburg, Ohio
Miamisburg ( ) is a city in southern Montgomery County, Ohio, United States. The population was 19,923 at the 2020 census. A suburb of Dayton, it is part of the Dayton metropolitan area. Named after the Miami people, Miamisburg is known for its industrial history, particularly its nuclear operations during World War II, and retail factors such as the Dayton Mall and surrounding commercial business area. History European-Americans started calling their first community "Hole's Station" ''circa'' 1797, when Zechariah Hole settled there with his family from Virginia and built a stockade on the west bank of the Miami River opposite the mouth of Bear Creek. The stockade attracted squatters, surveying parties, and other settlers who had taken grants to live in the local cabins until they could build their own; hence the little community became known as "Hole's Station". Settlers came west primarily from Pennsylvania. Miamisburg was incorporated in 1832 as a village; it achieved city ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
